When I visit San Francisco, I usually stay around Union Square and use public transportation. But with this visit, I'm driving all over the Bay Area "scouting" for venues and sites for an upcoming art & architecture tour. So I didn't want the hassle and expense of parking in the city. Of course, 4-star room rates are usually more reasonable outside the city too. My first bid was for $45, 4*, SFO Airport: rejected Added South San Francisco (no 4* properties there,) 4*, increased to $50: rejected Added San Mateo, 4*, kept it at $50: rejected Added Marina-Lombard St (no 4* properties there,) 4*, increased to $55: accepted! On the Marriott web site, this room is going for $219/night. Subtotal $220.00. Taxes/fees: $42.76. Grand total: $262.76. Of course, I used the PRICELINE link on the BetterBidding web site!
